Method of making a coated wire guide

摘要

In a method for making a wire guide, a fluoropolymer coating is removed from a distal section of an FP coated core wire to expose a metallic portion. A polymer coating is applied to a proximal section of the FP coated core wire such that the polymer coating overlays at least a portion of the FP coating, and to the distal section of the FP coated core wire including the exposed metal portion. The polymer coating is removed from the FP coating to form the wire guide having a proximal portion with the FP coating and a distal portion with the polymer coating. A hydrophilic coating may be applied to the distal portion over the polymer coating.

1. A method for making a wire guide comprising:
providing a metal core wire having a fluoropolymer (FP) coating disposed thereon defining a FP coated core wire having a proximal section adjoining a distal section, removing the FP coating from the distal section of the core wire to form an exposed metal portion; applying a polymer coating to the distal section including the exposed metal portion and to the proximal section such that the polymer coating overlays the exposed metal portion and at least a portion of the FP coating; and removing the polymer coating from the FP coating to form the wire guide having a proximal portion with the FP coating remaining on the core wire and a distal portion with the polymer coating.
